How do I display a score of zero?

[Bullfrog]

I've gotten to the point where I can display a score at the end of a Flash quiz including 'score-appropriate' comments such as: "You're a Flanders!" (if they do well, of course) or "D'oh!" if they do poorly.

But what if they score a Zero, get none right. (Moe?) What script do I need to return a score of '0' at quiz end?

Thank you in advance, you scripters of Great Knowledge...
